TERRY LOOM.

Application filed February 17, 1923. Serial No. 619,585

To all whom it may concern:

Be it known that we, WILLIAM DORIETY and (interns MAOARTHUR, citizens ofthe United States, residing at Paterson, lnthe county of Passaic andState of New Jersey, have invented certain new and useful Improvementsin Terry Looms, of whlch the following is a specification. v

This invention relates to those looms for weaving terry fabrics in whichthe reed s pressed backward in the batten for a suitable number ofpicks, during which the terry warp is floated, and then, the terry warpbeing again bound in by the weft, the reed is returned to its normalposition so that the first time it beatsup thereafter it sl des theintervening weft forward on the main warp and thereby packs it up to thecloth and 1ncidentally causes the floated warps to assume the form ofloops, it being understood that for this latter purpose the terry warpbeamrotatively yields independently of the main warp beam.

One object a terry loom having a simple, inexpensive and reliablecombination of parts whereby an endless variety. of designs or patternsmay bewoven. nother object 1s to make it possible, by changes readllyeffected, to apply a terry motion-to any ordlnary loom.

In the drawings,

Fig. 1 is a vertical sectional view of a loom embodying the presentinvention taken on line 1--1, Fig. 2;

Fig. 2 is a sectional front elevation of the left-hand end-portionthereof;

Fig. 3 is a plan of the forward portion Figs. 4c and 5 are vertical sectonal views through the batten and reed-structure, showing the means forcontrolling the latter in its two main positions Fig. 6 is a plan ofcertain parts of said means, the batten appearing in horizontal section;and p p Fig. 7 is a front elevationof certain parts appearingin Fig. 6.

The loom frame a, its breast beam b,the lay swords c upstanding from andsecured to the rock shaft 03, the lay or batten e carried by the layswords, the crank shaft 7 with the cranks of which the batten-1ncludingstructure d, 0, e is connected by the pitman g, and the cam shaft h areor may be all the same as in any ordinary loom. On the loom frame isarranged a pattern of this invention is to provide mechanism, here inthe form of anyordi nary dobby and used to manipulate the har ness' (notshown) ofthe loom. The dobby consists of a frame 2' in which arefulorumed jacks j to which the harness cords are adapt: ed to beattached, A: being levers pivoted to the jacks and having upper andlower.

pivoted hooks Z adapted to be caught and pulled outward, to move thejacks outward, by the upper and lower knives m which are caused bysuitable means of well knownconstruction and not shown to reciprocate inopposite directions; and n are the lifting wires for the respectivehooksl adapted to be raised'by the levers 0 which are made,

to rise and. fall by the pins p of a pattern chain Q which extends overa cylinder 1' that is rotated step by step by any suitable means (notshown),

The reed structure includes the reed s, the upperandlower horizontalbars 25 uin which the reed is setand end brackets 4; connecting thesebars. The lay swords have attached to them brackets to affording pivotsat m (Figs. 3, 4 and 5) for the reed struc:

ture, the pivots being actually engaged in holes in the end brackets 12.The reed may swing backwards on its pivots subject to the pressure ofspring plungers y arranged in suitable housings a on the lay swords.

Bolted to the back of the bar a at each end of the reed structure is afitting 2 in which ispivoted to move up and down a latch in the form ofa hook 3 which projects through a slot 4 in the batten and whoseshoulder 3 when the reed structure is fully forward, may abut a wearplate 5 set in the front of the batten and slotted to receive the hook.This wear plate is secured to the front of the batten by a screw 6 andalso by a lag screw 7 which has a long rearward extenslon 8 received bya horizontal hole 9 in the bar a of the reed structure, which hole iselongated transversely of itself and vertically lateral lost motion ofthe reed structure otherwise possible at the pivots 00 is prevented bythe extensions 8 of the lag screws 7 At the under side of the batten aresecured two brackets 10 in whichis arranged a rock shaft 11 having twolevers l2 fixed thereon. At their forward ends these levers have pivotedthereto upstanding push rods 13 which are guided in holes in a ledge 5proiecting from the wear plate and each of which has a rounded head 13*on which the s' norm breast been ere p nding hee s 3 t s Th end f h hookis 'tqrnied with a notch To the rear end of one of the levers 12 ispivoted a rod 14 which depends from the lever. The lower end of the rod14. is connected with a lever 15 fulcrumed in a bracket It;

Inthis way the terry, or looping of the terry warps, produced, the loopsbeing developed when, after each period when the reed structure ispressed back, the loom, starts to operate for a time with the reedstructure held for ward," Ordinarily, as explained, the fabric fromstart to finish would be siniple or plain terry (i. e., involving inalternation and t rough t he aving cert n umbe of picks when floating ofterry warp occurs and 3 6 7mm number (if picks when binding in of theterry warp with the main warp occurs), By our invention this terryweaving can becarried on for any selected extent lengthwise of thefabric (the reed structure being alternately pressed back and then heldforward, for nnn ber of picks desired to torinthe loops and bind in theterry warp with the main warp), and then plain weav ing can ensue forany desired extent lengthwise of the fabric, the reed being left heldforward by the hooks atsuch times. Thus a pattern will be, developed inthe'hfabric in which there will be lQQPQCl 0,1 terry portions extendingacross the fabric and of any desired width and intervening plain-weaveportions of any desired width. Many variations otthis are possibleespecially when groups of the warpsat intervals are all of then retainedas parts of the main warp, that is, are wonnd on the main warp, beain ndso a e not ubj c te h loop n t n. e e y i r s is t fa ric s a erna yformed terry weave and plain-weave, rec tangular terryligures will beproduced.
